ROADWAY.

Specification of Letters Patent.

Patented May 4, 1920.

Application led October 13, 1919. Serial No. 330,216.

To all 'whom t may concern:

Be it known that we, LUTHER P. TURNER and JOHN R. BURIuLL, citizens of the United States, residing at Spokane, in the county of Spokane, State of Washington, have invented a new and useful Roadway, of which the following is a specification. f

This invention relates to roadway construction, and the primary object of the invention is to provide a combination concrete or reinforced concrete and gravel earth, or other material roadway, wherein the concrete is formed into blocks or strips.

A further object of the invention is to provide means for `permitting the blocks or strips of concrete to expand and contract, with relation toeach other, without disrupting the road surface.

A further object of the invention is to provide means for connecting the coperating ends of adjacent blocks, whereby the blocks may be readily and efficiently conlnected, to restrict longitudinal and lateral movement of one member, with relation to the other.

With the foregoing and other objects in view which will appearas the description proceeds, the invention resides4 in the combination and arrangement of parts and in the details of aconstruction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings Figure 1 illustrates a fragmental view of a. roadway constructed in accordance with the present invention.

Fig.v 2 is a fragmental side elevational view of the adjacent ends of the concrete blocks.

Fig. 3 is a sectional view taken on line 3 3 of Fig. 2.

Fig. 4/ is a plan view illustrating a modified form of vmeans for connecting adjacent ends of concrete blocks, and

Fig. 5- is a fragmental side elevational view of the other modified form of end securing means. -l v l Referring to the drawing in detail, the reference character 5 designates the concrete blocks, employed in the construction of a roadway, according to the present in-A vention, and as shown, these blocks 5, are arranged in spacedl relation with each other,

and disposed in parallel relation with the sides of the roadway.`

In one form of construction, the blocks are provided with the parallel rods 6, embedded in one of the ends thereof, the rods 6 having portions 7' extending beyond the end wall of the block to which the same are secured, which extended portions 7 are designed to be positioned within the open-` ings 8, formed in the end of the adjacent block, the diameter of the openings being equal to the diameter of the rods 6, so that the rods 6 will be securely housed therein, to prevent lateral displacement of -one block with relation to the other; said socket 8 may or may not be metal lined and may extend into the block for reinforcing.

In constructing a roadway in accordance with Fig. 2 of the drawings, the adjacent ends of the blocks, are positioned in spaced relation with each other, which' posite end thereof, the nut 11, being adapted.

to move intol engagement with the plate 12, for clamping the plates 12 and 13, to the' adjacent ends of the blocks.

Each of these plates 12 and13, is substantially long, and provided with an integral flange 14:, which flange is adapted to lie within the space between the adjacent ends of blocks, to prevent movement of the plates with relation to the blocks, and as shown, each of these plates is provided with a centralv opening indicated at 15, which openings, ofV coperating lates, receive the transversely extending olt 9, which bolt, when properly positioned with relation to the blocks, clamps the plates 12 and `13, to Q end of the'opposed block being shown as provided with an elongated cut out portion 61to receive the extended ends of the rods 6.

This construction has been found in practice to be one which may be readily assembled, since the extended ends of the rods 6, may be moved into engagement with the side Walls of the cut out portion without the necessity of guiding the same thereto, as in the structure disclosed by Fig. 4 of the drawing.

With reference to Fig. l of the drawing, the roadway includes the blocks 5' which, as before stated, are supported in spaced relation with each other, the portions between the blocks being filled in with gravel, and topped with cement or other similar road dressings.

The construction as illustrated, restricts lateral, as well as longitudinal movement of the concrete blocks with relation to each other, and insures against the blocks, or ends thereof' moving with relation to each other,

to disrupt or otherwise render the roadway objectionable.

It might be further stated that these spaces between the adjacent ends of blocks, are filled with properly formed paper filler strips 16 which permit of a slight longitudinal movement between the adjacent blocks, and at the same time maintain the space between the blocks as closed.

Having thus described the invention, what is claimed is l. In a roadway construction, spaced parallel longitudinal blocks, the adjacent ends of the blocks being supported in spaced relation with each other, a bolt disposed within the space, plates supported on the bolt, and adapted to clamp opposite faces of adjacent blocks, and a filling material between the adjacent ends of the blocks.

2. In a roadway construction, spaced parallel longitudinal blocks, the adjacent ends of the blocks being supported in spaced relation with each other, a bolt positioned within the space, plates supported on the bolt, each of said plates having flanges positioned between the ends of the blocksA said plates adapted to clamp opposite faces of adjacent blocks, and a filling material'between the adjacent ends of the blocks.

- In testimony that we claim the foregoing as our own, we have. hereto affixed our sig* natures in the presence of two witnesses.
